UV LIGHT ON DURING NIGHT DURING FLOWERING PERIOD THEORY!

[Alexander Supertramp]

UVB in moderation is a legitimate way of increasing resin production. I just dont think I would use it during the dark period. You use it for short periods during the lights on period. Look into some of RM3s posts to see for yourself.

Going on your 5th edit, here. Are you quite finished?

Troll much?

Finally somebody with some actual experience using uv lights...... Oh, wait. Never mind. Unless...... Wait...... Do you have any?

The fact is that a high power HID requires a spacing from plants otherwise they will burn. Lower power lights do not require that space, so more plants can fit within the same room. The best use of a space from my reading and knowledge, not experience would be a shelved warehouse with top lighting. That way vertical space isn't wasted with the top lighting design. Also tends to be the design used in the biggest hydro companies.

Lower power lights also lack in intensity and require closer placement and constant repositioning to remain effective. Not to mention, that even distribution of light like you're suggesting means a lot more, less powerful lights, which means effectiveness is limited by space, with a small tubular shape being most efficient (hence the trashcan).

So, when I was in college the best use of space for me was that trashcan. But now that I have more space and want to run vert, it makes no sense to purchase hundreds of smaller lights that are going to need constant adjustmant and monitoring, not to mention the costs involved here. Instead of keeping a multitude of smaller lights hanging around my canopy, I'd rather position my canopy with optimum distance of a hanging HID bulb.

If I wanted to pull more than a pound a plant I could set up a 12x12 room where P is a plant (vert tree) and X is an HID. Each plant on this scenario is receiving tridirectional HID lighting, much more effective and intense than CFLs or LEDs could ever get.

All these lights have their niches, but CFL and LED don't, IMO, have much of a place in large scale vertical setups because of inherent limitations of the techs themselves coupled with need for high intensity lighting.

The only reason the trashcan works as effectively as it does is because the can is only 2ft across. With multiple points of light distribution on the inside I can be sure that a plant inside is covered with light. But start to increase the diameter of the space and you begin running into problems with keeping a consistent (in intensity) level of light within the space. The solution become High Intensity Discharge lighting, and placing plants around the bulb, or bulbs in between plants.

I think the gains from vert would offset the loss of a few square feet of space, not to mention the whole concept of vert is to more efficiently use the same square footage anyways...

The trouble with this post is that you're debating someone who claims knowledge and experience in the same sentence as admitting he's never done it.

I'm on record elsewhere in this forum as walking my talk- with HID lighting.

 

[ttystikk]

Sounds legit.

TOTALLY.

I have actual UVB experience, many of us do, you can go to hell. If anyone takes you seriously they haven't run into you, look at all the never-ending trolling you can find looking at your post history. I don't see much of value that you have shared, just seem to like spinning things to get your rocks off.

Please quote this sentence you refer to, or this is an unfounded attack and you should be ashamed.

You don't like that I can know something without personal first hand experience. Too bad for you, you if you can't accept that you must only have the capability to learn through direct experience, and that is a sad mental condition to have.

Constant repositioning? Why? Just many more of them much closer...

Yes with a wider room you would have to have something like floating CFLs or rope lights to keep it consistent if the room is more than 3-4ft wide. I don't see how HID can be considered consistent in intesity in that same space however. Only way it can be consistent is if you exclude 1/3 of the grow space for bulb placement, that exclusion of space takes the teeth out of the consistency argument.

I think the real argument is it's a complicated bitch to use low power bulbs/emitters and most people would prefer to stick to something more simple.

Been usin UVB for years, IME UVB increases potency, tis the deep blue at the bottom that grows more trics, I use Coral bulbs for that

I have 1 UVB bulb in veg (because I breed) and I do have pics of baby seedlings all aimed at it, Plants def respond to UV so I would not run em during the dark period

I do and use them. Quite effectively by the way.

Not sure about your UVB bulb, but the ones I'm using put out UVB, UVA, and a good deal into the visible blue light. Only 10% is UVB, about 40% UVA and the rest is visible blue/deep blue light. So I guess I can't say for sure if my results are due to UVB or UVB + Deep blues or just Deep blues, but I can say the 6500k LEDs don't have near the resin/thc effect as the UVB bulbs and they also hit most of the blue range. I will have to play with a coral bulb or similar LEDs in the future and see what happens.

I use ATI Coral Plus, added separately after the UV bulbs so I'm pretty sure bout it
same plants and such, big difference

here are the spectrum's of the bulbs I use

The True Actinic (I have 3 in flower & 1 in veg) and the Coral plus (5 in flower and 2 in veg)
